In the past years, several approaches have been developed to generate complex optical potential profiles [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}. Most of them rely on the development of spatial light modulators (SLMs), which can modulate the phase or the intensity of a light beam. Digital micromirror devices (DMDs) are one of the most widely used in cold atom experiments thanks to their low cost, simple use and high refresh rates. They consist of millions of individual micromirrors which can be set in two different orientations, hence corresponding to a “black" or “white” signal in a chosen image plane of the DMD chip. They have been used to correct optical aberrations when working as a programmable amplitude hologram in a Fourier plane [9]}, and to produce different potential profiles by direct imaging [7]}, [11]}, [12]}, [13]}.
